soundboardinstal again

[Delwin D Fandrich]

It's kind of the question he answered. I can't imagine any real-world
conditions under which a soundboard would "splay-out" by as much as 1/4". A
few thousandths of an inch, yes, but 1/4"? There is not that much crown in
an actual soundboard. And it is not compressed that much when it is glued
in.

This can kind of fool you at times since the ribbed soundboard can be
pretty distorted before it finally gets glued down. Things do move about
some.
